Mugiwarah: Have you read the Steam Subscriber Agreement or are you trully believe that Vavle or any Store can't remove your game?
They call "your" games a subscription and it's clearly written that they can remove it from your account. They probably haven't remove a lot of games beside keys from grey market but it doesn't mean they can't, they have the right to do it and you gave them the authorization to do it by accepting the TOS.
Shocker93: They can only make live service games unavailable. They don't remove anything that isn't live service. I have games that are both from the store, and were activated via keys, and all of them are there and playable. They don't remove your games. Period.
It’s true that when a game is delisted from the store, it’s usually not removed from players' libraries. However, you’re conflating two different things here: delisting a game is not the same as removing it.
There have been cases where games were removed from users’ accounts, most often with online multiplayer titles where servers were shut down and the publisher requested removal. But legally, this doesn’t just apply to online games. If a license holder runs into legal trouble, for example, losing the rights to distribute a certain IP, or it turns out they never had that right to start with, then the license may be revoked, and as a result, the game can be pulled from users’ accounts as well.
Additionally, games can be removed if the key used to activate them turns out to be illegal, whether it’s a fake, part of a scam, or linked to credit card fraud. (One common method of laundering stolen credit cards is to quickly buy game keys and then resell them on grey market sites.)
Bottom line: while it’s uncommon, Steam does have both the legal and technical ability to remove games from your library.
